当使用液体次氯酸盐时，饮用水中的氯酸盐离子可能有三种来源。一个来源是原水本身。第二个来源是消毒过程中残留的次氯酸分解。第三种来源是OCL原料溶液在使用前储存期间的分解。基于一系列初步实验，作者认为，饮用水中ClO3-出现的主要途径来自储存期间液体次氯酸盐的分解，用于FAC消毒。支持这一假设的直接证据是本文的重点。通过详细的速率和机理研究，观察到了ClO3- 形成可以概括。稀释初始OCl-浓度比降低温度更有效地降低ClO3-的形成；然而，稀释和较低的温度都可以有效地减少高碱性OCl原料中ClO3的形成。除了减少OCl原料中OCl生成量的具体建议外，作者还描述了NaOCl溶液中的有效氯含量；半衰期、反应级数和反应速率；NaOCl中氧生成速率常数的测定；分析商业化生产的NaOCl；以及金属离子对氯酸盐离子形成的影响。

There are three possible sources of chlorate ion in drinking water when liquid hypochlorite is used. One source is the raw water itself. A second source is from the decomposition of residual hypochlorous acid during disinfection. A third source is from the decomposition of OCL- feedstock solutions during storage prior to application. Based on a series of preliminary experiments, the authors believe that the major pathway by which ClO3- appears in drinking water originates from the decomposition of liquid hypochlorite during storage for use with FAC disinfection. Direct evidence in support of this hypothesis is the focus of this paper. As a result of detailed rate and mechanistic study, observations with respect to ClO3- formation can be generalized. The formation of ClO3- is more effectively lowered by diluting the initial OCl- concentration than by decreasing the temperature; however, both dilution and lower temperature can be effective in minimizing ClO3- formation in the highly basic OCl- feedstock. In addition to specific suggestions for decreasing the amount of OCl- formed in OCl- feedstock, the authors describe the available chlorine content in NaOCl solutions; half-life, reaction order, and reaction rate; rate constant determination for oxygen formation in NaOCl; analysis of commercially produced NaOCl; and the effect of metal ion on the formation of chlorate ion.
